Hi Virgil,
<i><font color="#663300">How does one handle an update that involves child records.</font></i>
That's the beauty of the way the cBizObj is designed. You can create an hierarchy of business objects that matches your data model. Each business object instantiates an oRefBixObj collection in the Load Event the cBizObjForm.ResolveBizObjs method populates that collection in each business object according to the cParentBizObj field of each business object or if that is blank, makes all the objects children of the primary business object.
<i><font color="#663300">Assuming that the data entry for the invoice and items is handled on the same form, does one place two business objects on the form?</font></i>
In the two main forms of one of our applications there are 8 and 10 business objects respectively.
